combine objects by name in scene into one object
You can use the startswith() function to select all the objects that stqrts with Verts and join them into one object :

import bpy

bpy.ops.object.select_all(action='DESELECT')
objects = bpy.context.scene.objects
for o in objects:
    if obj.name.startswith("Verts") :
        obj.select = True
bpy.ops.object.join()
